This text introduces engineering concepts of motors and drives in a way that can be understood by both engineers unfamiliar with the technology and by technicians who are technically literate but not accustomed to complex theory and mathematics. It features simple explanations, summaries, reviews questions, glossaries, and reference tables for formulas and conversions. The text begins with an explanation of the principles of DC and variable frequency AC drive technology, then goes on to cover DC and AC motor and drive operation, step motors, AC vector motors, servo motors, and vector drives. Feedback devices such as tachometers and encoders are also addressed as they relate to speed and torque control. Later chapters cover drive systems control methods and the maintenance and troubleshooting of drive systems. Polka is a training center manager. Annotation c.
